Patent JP-S6035339-A (JP)
Title: Optical reader
Inventor: TAKASHIMA MITSURU
IPC: G11B7/09
Filed: 1983-08-03
Abstract: PURPOSE:To eliminate the need to adjust the photodetection surface of a photodetector in a focusing direction by detect a focus error from the mean quantity of reflected light from a flank of a reflecting body, and eliminating the need to work the reflecting body with high precision and also selecting a desired reflecting body. CONSTITUTION:A focus error signal is obtained as SB-(SC1+SC2) by photodetection areas B and C (C1 and C2), and focus control is performed on the basis of the focus error signal. When a disk D is displaced approaching an objective lens 4, the SB-(SC1+SC2) becomes negative. When the disk D moves away from the objective lens 4, the SB-(SC1+SC2) becomes positive. Then, an optical system is moved into an in-focus state so that the output difference SB-(SC1+ SC2) is eliminated, performing the focus control. Further, the reflecting body 5 differs in height in the optical-axis direction of return luminous flux and is selected and replaced easily, so the outer circumferential part of the luminous flux is projected and adjusted, eliminating the need to adjust the photodetection surface of the photodetector P in the focus direction.

Title: Distribution arrangement table creating method
Inventor: NAGASAKA MASAYUKI
IPC: H04L12/28
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To reduce a table creating time used for the processing, such as band assignment of a virtual channel in an ATM sharing service, decrease fluctuation of a placed position and enhance the placing rate of processing objets. SOLUTION: When a processing object cannot be placed at an n-th placed position 1-1, that is one of ideal positions set at a uniform periodic interval and at which each processing object is to be placed because other processing object has already been placed at the n-th placed position 1-1, an idle position at which the processing object is placed is sequentially retrieved up to an (n-1)-th ideal position 1-2 by one position in front of the n-th ideal position, the processing object to be placed at the n-th ideal position is placed to an idle position possible for placing detected by the retrieval. When the idle position possible for placing cannot be detected up to the (n-1)-th ideal position 1-2, disabled placing is discriminated. Furthermore, the phase of the initial position is changed to retrieve and set the initial position that provides a small fluctuation and a high placing rate.

IPC: B23K9/20
Filed: 1979-11-01
Abstract: PURPOSE: To obtain a uniform weld zone by welding the stud of a stainless steel at opposite polarities in an atmosphere consisting essentially of an Argon gas.  
     CONSTITUTION: The arc is generated at the opposite polarities at which the polarity of the stud becomes plus and that of the work minus, and during this time, the arc and molten pool are shielded from the atmosphere by a shielding gas consisting essentially of an Argon gas. As a result, the arc 4 generates approximately uniformly from the approximate center of the stud 1 and the molten metal 1b at its end part 1a becomes a small particle; in addition, the molten metal 2a of the work 2 also assumes a wide and shallow tray shape. Hence, the uniform deposited metal 2b and reinforcement of weld 2c may be obtained for the weld zone after ending of welding.

IPC: H04N1/04
Filed: 1990-05-31
Abstract: PURPOSE:To simplify and miniaturize a circuit and the structure by forming a reflection face on the inside surface of the transparent glass tube of a straight lamp and forming a light throwing aperture, whose aperture width in the peripheral direction of the glass tube is gradually reduced from the center part toward both ends of the glass tube, in the reflection face. CONSTITUTION:A reflection face 3 is formed on the inside surface of a transparent glass tube 2 of a straight pipe type lamp 1, and a light throwing aperture whose aperture width in the peripheral direction of the glass tube 2 is gradually reduced from the center part toward both ends of the glass tube 2 is formed in the reflection face 3. Consequently, the angle of irradiation of light from the lamp 1 is gradually narrowed from the center part toward both end parts, and therefore, the quantity of condensed light on a read line is limited to a certain value because of diffusion of light in the case of the center part where the angle of irradiation is wide, and that is raised to the certain value because of limitation of diffusion of light in the case of both end parts where the angle of irradiation is narrow, and the quantity of light is uniformized in respective parts. Thus, the circuit and the structure are simplified and miniaturized.

IPC: G02B7/10
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To suppress the unnecessary driving of a lens driving means, after a zoom lens is housed and further, the generation of a howl and noise by controlling the lens driving means, with a housed state detecting means. SOLUTION: When the power supply switch 70 of a projector is turned off, a driving control means 40 outputs a driving control signal to the lens driving means 20, to start the housing operation of storing the zoom lens 10 in a projector main body and a counting up operation by a time information calculating means 50. When the fact that the zoom lens 10 becomes a fixed housed state is detected by the housed state detecting means 30, the driving control means 40 allows the zoom lens driving means 20 to stop the operation of housing the zoom lens 10 and stops the counting operation by the time information calculating means 50. Then, the drive control means 40 stores the obtained count value in time information storage means 60. Thus, time information up to the fixed housed state is obtained.
